chirpstack-gateway-bridge doesn't seem to be up

[symeonmattes]

Hi,

I have used the docker-compose.yml to setup my docker environment through docker-compose. Although everything seems to be up and running, the chirpstack-gateway-bridge is not up. The docker yes, but not the service inside the docker.

For simplicity I have run only bridge and mosquito, i.e.

docker-compose up chirpstack-gateway-bridge

With docker ps I have:

CONTAINER ID   IMAGE                                         COMMAND                  CREATED          STATUS          PORTS                                       NAMES

symeon@debian:/media/extra_partition/MyProjects/MbedPrograms/Prototypes/server-prototype-environment$ 

I login to mosquito container with nmap installed: docker exec -u 0 -it a2663bda40d9 /bin/sh

Starting Nmap 7.80 ( https://nmap.org ) at 2021-07-11 17:25 UTC
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000090s latency).
Other addresses for localhost (not scanned): ::1
Not shown: 65499 closed ports
PORT     STATE SERVICE
1883/tcp open  mqtt

And then I login to bridge: docker exec -u 0 -it 0246623d4ae2 /bin/sh

 nmap localhost -p 1-65535
Starting Nmap 7.91 ( https://nmap.org ) at 2021-07-11 17:26 UTC

Other addresses for localhost (not scanned): ::1
All 65535 scanned ports on localhost (127.0.0.1) are closed

Nmap done: 1 IP address (1 host up) scanned in 1.27 second

The bridge doesn't seem to be up...Is it a bug or should I do anything else?

In https://github.com/brocaar/chirpstack-docker/blob/master/configuration/chirpstack-gateway-bridge/chirpstack-gateway-bridge.toml

I have tried also to use the ip of the mosquito container which in my case was

[integration.mqtt.auth.generic]
servers=["tcp://172.20.0.8:1883"]     | instead of tcp://mosquitto:1883
username=""
password=""

But again nothing is up

Are you sure you are scanning for UDP ports?

Hi @brocaar

You're very right...I didn't notice it's UDP.

Thanks Cheers
